I have an Akra slip on and am considering adding an x pipe. I'm in CA so I'm concerned about smog testing. I've read on other forums that it is difficult to pass the sniffer with 100 cell cats but pretty easy with 200 cell cats. I've asked several sponsors about getting 200 cell cats on the Akra mid pipes and they all say it isn't possible. Do you think I need 200 cell cats and how do I get in touch with IND? Also, are the primary cats and thus the O2 sensor affected?
